Color - First Steps
One of the first successes in color photography was
demonstrated in 1861 by the Scottish physicist
James Clerk Maxwell (1831 - 1879).
Maxwell devised a way to recreate the colors of a tartan
ribbon. He had three negatives of the ribbon made, each
through a different color filter - red, green and blue.
Positive black and white transparencies were
made of the three negatives. While projected
superimposed though three color filters like
those on the camera, the three positives
produced an image of the ribbon in it’s original
This technique is called “additive color mixing”.
Colors are produced by adding together varying
amounts of red, green and blue.
